GLOBE SUPPORT.

- i Application filed July 26, 1923. Serial No. $5 3,866.

To all whom it may concern:

v Be it known that I, lVILLiAM C. IIOMAN, a citizen of the United States of America, and a resident of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Globe Supports, of which the following is a specification.

' The present invention relates to globe supports and method of making the same,

and more particularly to a type of circular globe support suitable for holding globes for electric or gas fixtures.

These globe supports should be light in weight, easy to assemble and to manipulate,

and of'comparatively inexpensive construe-j tion. In order to secure a light weight structure, these supports have "heretofore been made out of blanks of sheet metal by suitably punching or stamping the same. An example of such a holder'is shown in Van'Gelderen Patent No. 1,071,537, granted August 26, 1913. In making up the circular and the arcuate parts of this type of globe support out of sheet metal, it is impossible to avoid a large percentage of waste material. An object of the present invention is to make the movable parts of the globe holder without appreciable waste of material, thereby economizing the same.

A further object of the present invention is to make parts of the frame out of wire, preferably steel, pressed to shape.

Another object of the present invention is to provide a compact globe holder which may be readily assembled out of light weight but strong parts.

The accompanying drawings show for purposes of illustrating the invention, one of the many possible forms in which the present invention may be embodied. In these drawings:

Fig. 1 is a vertical section showing the shade holder mounted in a canopy, the globe being released; and

Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1, the parts being in position toclamp the globe in place.

In Fig. 1 a canopy 10, which may be of any suitable shape and size for the particlular globe which is to be used, is provided with a short, cylindrical lower skirt portion'll underneath an annular shoulder 12, and with a bead 13. The globe support, which forms the subject matter of the present invention, is mounted inside the cylindrical portion 11 of the canopy. An annular ring or casing 14:,- which may be made of a sheet metal stamping, has an inwardly turned lower flange 15, and is of the proper size to.

'fit loosely inside of the cylindrical portion 11. The flange 15 is provided'with a plurality, 1n the present case three,holes'16 for rivets 17. These rivets provide pivotal mountings 1.

for three globe clamping members-18. Di

rectly above the globe clamping members there is shown an annular shaped actuating ring 19 which has a plurality of holes. or slots 20 to receive the upwardly bent end 21 of the globe clamping members 18. 'The ring '19 is provided with a block 22 which may be riveted to it as-indicated and this block is provided with a threaded. stud 23 which passes outwardly. through a slot 24 in the side wall of the ring 14 and through a slot 25' in thecylindrical portion 11 of the canopy. 5

- It will be noted that the actuating ring and arcuate clamping members are of such shape that, if made out of sheet metal by punching, there: would .be considerable waste. According. to the present invention. however, these members: are made-out of flattened steel wire." The round wire is passed through suitable dies or rolls to flatten it to the desired thickness and width, and the flattened wire is then wound into a helical coil of the proper diameter after which the wire may be tempered or be treated as desired so that itwill remain permanently in shape. The coiled wire is then cut to provide pieces of the proper size. In the device as shown in the drawings, one complete coil of the helix is severed to provide the actuating ring 19 and three semicircular pieces of the flattened wire are sev- 1Ke)red to provide the globe clamping memers.

Each of the globe clamping members is punched to provide a hole 26 for the rivet 17 while the other end 27 of the member is formed to the shape shown by bending up the end 21 and cutting away the slight amount of excess material along the line 28. The ends 29 and 30 of the actuating ring 19 are brought together and fastened by the rivets which hold the block 22 in place. These parts may be assembled in the ring 14. by first riveting the clamping members 18 in place, then bringing the ring 19 down underneath the prong 31 which has been struck inwardly from the ring 1 1. The ring 19 and the ends of the clamping members 18 are suitably disposed so that the upturned ends 21 may enter the slots and the stud 23 is passed down through a vertical slot 32 which communicates with the slot 24L. To assemble this device in the canopy, the stud 23 is pushed out through the slot 25 and the ring 14 and the parts carried thereby are moved into the position of Fig. 1. A thumb-screw or wing-nut 33 is threaded on to the stud 23 and a screw 34 is passed thrmigh the walls 11 and 14 to secure the parts in place.

To clamp a globe 35 or other device in place it is raised t the position as indicated by dotted lines in F ig. 1 whereupon the actuating ring is moved toward the position indicated in Fig. 2, the projecting stud being available to 'move the ring. The ring is guided by the stud and the prong 31, and by its movement carries the movable ends of the globe clamping members a short dis tance, swinging these members on their pivots and bringing them int the position of Fig. 2. The thumbscrew or wing-nut may be tightened against the canopy thereby fixing the parts in position.

The globe retainer Which has been de scribed is a very light weight structure and utilizes material efficiently and without waste. On account of economizing material and being very easy to assemble, it has been foundthat this type of globe support has considerable advantage over those made out of sheet metal stampings.

\Vhile the structure'disclosed has three clamping members it is of course obvious nally flanged sheet metal ring, the flange having a plurality of regularly spaced apertures an actuatin r1n of flattened wire a n a spaced above the flange, the ring having a plurality of regularly spaced apertures, and a plurallty of sem -circular flattened wire globe clam nn members intermediate the z D v fiance and actuatin rum and nvoted 1n the apertures.

23. A shade holder, comprising an inter nally flanged sheet metal ring, the flange having a plurality of regularly spaced apertures, an actuating ring of flattened wire spaced above the flange, the ring having a plurality of regularly spaced apertures, a plurality of semi-circular flattened wire globe clamping members intermediate the flange and actuating flange ring, and pivoted in the apertures, the side of the ring having a slot, a stud passing through the slot, and a clamping nut on the stud.
